This comprehensive guide provides a detailed, step-by-step process for disassembling and reassembling the fire control group (FCG) of a Glock 19 pistol. This is crucial for maintenance, cleaning, and potential upgrades. Always prioritize safety and handle firearms responsibly. Improper handling can lead to serious injury. If you are unfamiliar with firearms or feel uncomfortable performing this task, seek the assistance of a qualified gunsmith.
Tools Required
Before you begin, ensure you have the following tools:
- A properly sized punch: This is essential for safely removing pins. Avoid using improvised tools. A Glock specific punch set is recommended.
- A nylon or plastic mallet: Metal hammers can damage parts.
- A clean workspace: A well-lit, clean area free of distractions is critical.
- A container for small parts: Losing a tiny spring or pin can halt the process and potentially damage your firearm.
- Gun cleaning solvent and brush: Cleaning the FCG is a vital part of this process.
- Fresh gun grease and oil: Appropriate lubrication is key to reliable operation after reassembly.
Step-by-Step Disassembly
1. Safety First: Always ensure the firearm is unloaded and pointed in a safe direction. Visually inspect the chamber and magazine well.
2. Removing the Trigger Housing Pin: Using your punch and mallet, carefully drive out the trigger housing pin. This pin is located at the rear of the trigger housing. Use firm, controlled taps.
3. Separating the Trigger Housing: Once the pin is removed, the trigger housing will separate from the frame. Carefully remove the housing, being mindful of the small springs and components within.
4. Disassembling the FCG: Now you will begin taking apart the internal components of the FCG. This step often involves removing a connector pin, usually located near the trigger bar. Consult your Glock 19 specific manual or diagram for precise locations and instructions as the exact layout may vary.
5. Removing the Trigger Bar and Trigger: Once the connector pin is removed the trigger bar and trigger can typically be removed; carefully note the position and orientation of each component as you proceed.
6. Removing the Sear and Disconnector: These components are small and delicate. Handle them with care. Again, consult your manual or diagram for specific orientation and instructions. A misplaced or damaged component can render your firearm inoperable or unsafe.
7. Cleaning and Inspection: Once completely disassembled, thoroughly clean all components using your cleaning solvent and brush. Inspect each part for wear, damage, or any signs of breakage. Replace any worn or damaged parts.
Step-by-Step Reassembly
1. Prepare for Reassembly: Lay out the components in the order you plan to install them. Using diagrams from your Glock 19 manual will be helpful.
2. Reinstalling the Sear and Disconnector: Carefully install the sear and disconnector in their correct orientations. Ensure they are securely seated before proceeding to the next step.
3. Reinstalling the Trigger Bar and Trigger: Carefully place the trigger bar and trigger back into position. Be mindful of the precise fit and any interaction with other components.
4. Reinstalling the Connector Pin: Place the connector pin back in the trigger mechanism and gently tap it into place. Avoid using excessive force.
5. Reassembling the Trigger Housing: Gently seat the trigger housing back onto the frame, ensuring all components are aligned properly.
6. Reinstalling the Trigger Housing Pin: Using your punch and mallet, carefully drive the trigger housing pin back into place. Ensure it is fully seated.
7. Function Check (Important): After reassembly, perform a thorough function check. This involves dry-firing the pistol (without ammunition) several times to ensure all components are functioning smoothly. Never point the firearm at anything you are not willing to destroy.
8. Lubrication: Lubricate all moving parts of the FCG with appropriate gun grease and oil.
Important Considerations
- Consult your Glock 19 Manual: This guide serves as a general overview. Always refer to your Glock 19 owner's manual for specific instructions and diagrams tailored to your firearm.
- Professional Assistance: If you are unsure about any step, seek the assistance of a qualified gunsmith. Improper disassembly or reassembly can lead to malfunction and potential injury.
- Safety First: Prioritizing firearm safety is paramount throughout the entire process.
This detailed guide provides a comprehensive understanding of the Glock 19 FCG disassembly and reassembly process. However, remember, working with firearms requires caution, responsibility, and proper training. If you have any doubts, consult a professional.
